2. Forage mass and stocking rate of elephant grass pastures managed under agroecological and conventional systems
The objective was to evaluate elephant grass (Pennisetum purpureum Schum.) pastures, under the agroecological and conventional systems, as forage mass and stocking rate. In the agroecological system, the elephant grass was established in rows spaced by 3.0 m from each other. During the cool season ryegrass (Lolium multiflorum Lam.) was established between th

3. Proposta metodológica de medição da resiliencia agroecológica em sistemas sócio-ecológicos : um estudo de caso nos Andes colombianos / Methodological approach for measuring the socioecological systems qualification resilience: a case study in the colombian Andes
In the last tree centuries the capitalistic economic model introduced deep changes and with no precedents into the ecosystems with the aim to satisfy its own food demands, potable water, wood, fiber and energy. Those changes helped to improve the life of thousands of people, but at the same time weakened natures regulation capacity. The most evident conseque

4. Sistemas agroflorestais e a construção do conhecimento agroecológico em assentamentos rurais / Agroforestry systems and agro-ecological knowledge construction in rural settlements
The Sepé Tiaraju, the first one settlement in the mode of Sustainable Development Project PDS of São Paulo state, founded in 2004 in the sugarcane region of Ribeirão Preto/SP, has as a proposal being an alternative to the conventional forms of land occupation and management of natural resources adopted in the region. Then a group of farmers along with Emb

5. Agroecological innovations for household farming: a case study on the agroforest systems in Upper Jequitinhonha / InovaÃÃes agroecolÃgicas para a agricultura familiar: um estudo de caso sobre sistemas agroflorestais no Alto Jequitinhonha - MG.
The process of modernization of farming brought about significant transformations in Brazilian rural milieu. The âgreen revolutionâ was considered by many authors a harmful model in environment and socially excluding. It was characterized by the standardization of the agricultural production processes, disregarding the countryâs regional particularities.

6. Indicadores de qualidade do solo sob sistema de produção agrícola convencional em conversão para agroecológico
Microbial and biochemical indicators of soil quality, mainly those related to carbon and nitrogen cycling, are useful to access the effect of soil management and its effects on the sustainability of the agroecosystems. The aim of this work was to access changes occurring in the soil due to the transition from conventional to agroecological agricultural syste

7. Monitoramento do uso da terra e dos níveis de nutrientes do solo no Sistema Integrado de Produção Agroecológica utilizando geoprocessamento. / Monitoring of land use and soil nutrients levels on an integrated agroecological production system by image processing.
Agroecological production systems are more complex than conventional ones, since a series of crops follow in sequence or are intercropped to achieve high diversity and maximize soil nutrient recycling. The full understanding of these systems require systemic analyses and therefore, adequate tools. To understand soil fertility evolution, heterogeneity should

8. Agroflorestas sucessionais no assentamento Fruta D anta - MG: potenciais e limitações para a transição agroecológica
This research was based on a case study at Fruta DAnta settlement, a rural community located at João Pinheiro, Minas Gerais, Brazil. At the site was possible to note how the conventional agriculture technologies and the idea of productivism are great part of the production dynamic and define the agroecosystems design implanted by the local farmers. Consorti

9. Produção de sementes de cebola em sistemas convencional e agroecológico / Onion seeds production in conventional and agroecological systems
The present work had the objective to study conventional and agroecological systems of onion seed production. For that, three proprieties of agroecological production in Candiota and Hulha Negra, Rs, were followed and two conventional were used. They were at random and six sub samples were taken from each experimental unit, each of them with two meters over

12. The Meaning of Sustainability : Searching for Agri-environmental Indicators
This thesis investigates the sustainability of peasant or family farm agriculture in the south of Brazil. Two different technological approaches adopted by those farmers were scrutinized: the agroecological and the conventional technological systems. A methodology to identify agri-environmental indicators, which could embrace the environmental, economic and
